i SPECIFICATION forming part of Letters Patent No. 370,599. dated September 2'7, 188'?.

Application tiled February 1B, 1887.

To all whom' it may concern.: y

Be it known that l, JOHN K. BITTENBENDER, of Bloomsburg, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in Fountain- Pens; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to au improvement in fountain-pens.

Hitherto in that class of fountain-pens in which a reservoir-holder has one of its ends permanently closed, and a penholding plug is secured in the opposite end of the reservoirholder, more or less trouble has arisen in filling the reservoir and' in securing a free dow of ink to the pen-point under all circumstances of ordinary writing without rendering the holder liable to waste ink when subjected tor a sudden jar. In many instances it has been I necessary to use a pen of some particular construction different from those in ordinary use.

The object of my present invention is to provide a fountain-pen which shall be free from the objectionable features above enumerated, and which shall have no small eparable attachment in its structure.

A further object is to provide a fountain pen -holder which shall be adapted to ilse in connection with all ordinary forms of pens, and which shall consist of few parts, and these of such construction as to render them capable of being manufactured at slight initial cost.

With these ends'in view my invention cou-l sists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is la view of the fountain pen-holder and pen in longitudinal section, showing the point of the main feeder in the position relatively tothe pen-carrying plug which it occupies when the pen is in use. Fig. 2 is a similar view,showing the point of the main feeder in the position relatively to the pen-carrying plug which-it occupies when the pen is not in use; and Fig. 3 is la transverse section through line :v a: of 6, and 7 are modifications.

able size and shape, permanently closed at its end a, and open at its opposite end to receive the pen-carrying plug B. The open end ofthe holder A is preferably provided with an interior screw-thread, C, adapted to register with a male screw-thread, c, on the upper end of the plug B. rIhis construction'is not, however, necessary, since the end of the plug B might be constructed with a smooth surface adapted to fit within a smooth bore in the open end of the 4holder A, and be held therein in tact therewith.

The pen-carrying plug B is provided with a slit, D, extending from its lower end to a conical-shaped or Haring opening, d, in its end toward the reservoir within the holder A. The slit D is of such size and length as to admit the stock of any ordinaryI pen-such as isin common use-and allow the upper end of the stock to extend to the point where the opening d begins to flare. The pen-carrying plug B is' further provided with an outwardly-daring or funnel-shaped flange,E, around its lower end, and with auxiliary feeders F f,projecting from the base of the ange E along the upper and under sides of the pen G when the latter is in its position within the slit D. The Nauxiliary feeder F,which extends along the topl of the pen toa point points of the nibs of the pen, is providedwith yone or more `capillary channels, g, extending along its under side and continuing along the interior wall of the plug B above the pen to the opening d. The auxiliary feeder f extends to a point beneath the pen about where the nibs unite with the stock of the pen, and is,l

provided with one or more capillary channels, g', extending along its upper face and continu- Ving along the interior-wall of the plug B beneath the pen to the opening d. The feeders the desired adjustment by its frictional conbetween and near the extreme v F f are narrow and' of slightly'tapered form, Y and are constructed of material which is. more or less iiexible-hard rubber, forexampleto admit of their yielding to the movements of the pen.

H represents the main feeder. It consists closed end of the holder and extending along tube permanently se't in the the interior of the reservoir to a point at the neck of the opening d, where Yit preferably function, as follows:

find it preferable to employ as the main 5 feeder a small tube provided with transverse perforations h/through which there isareadycommunication between its interior and the reservolr, the lower end of the feeder being left open. In the place of the said tubular main feeder a channeled rod-such as is represented in Fig. 2-mightbe employed,andwould give'a fair degree of satisfaction; or a simple be employed, and could be furnished at a trle less cost than the perforated tube show 1n my preferred construction, Fig. 1.

The main feeder H performs a threefold In filling the reservoir it causes the ink to adhere to it and travel toward .the permanently-closed end of the reseryoirin a well-.defined stream,

without abruptly meeting ythe indowing ink and producing the objectionable bubblingand scattering of small particles of ink, which is liableto taire place as the ,bubbles of com- 4pressed air one after another burst. vThe said main feederalso serves to feed liability of the supply being abruptly cut off back-pressure of air,I and when the B is inserted within'the holder A suilstoppage of one or both of the channels gg.

To adjust the pen for use the Plug B is slightly'advanced out of theholder to free the The supply will in every instance l The slight lifting of theauxillary feeder F from the upper side 0f :the pen as its point is bent upwardly and the slight uiting of the auxiliary feeder-ff from the under side of the pen as its point is bent downwardly, will produce a suctionJ of greater or lesser power as the stroke'is heavy or light, and will thereby draw the inkttlw points of the nibs in greater or lesser quanti* ties, and in no instance will there be liability. as the capillary channels are long and narrow, and buta slight surface of the ink is exposed to the open air.

Should the ink under any circumstances tend to creep out onto the stock of the penand overload the same,

guide it away from the stock of the pen and prevent any annoyance therefrom.

` hence I donot wish to limit l the funnel-Shaped flangev around the lower end of the plug will tend to.

It will beobserved that the fountain-pen as l thus constructed consists of two separable parts only-viz., the reservoir-holder with the 7o main feeder permanently attached therein and the pen-carrying plug with its auxiliary feed# ers and guard-flange formed integral therewith or permanently attached thereto.

A cap, P, is provided to t over the pen- 75 carrying plug when the pen is not in use. Its

operation is so simple that any one can ma-l nipulate it with/ease, and its construction is such that it can be furnishedat'a very moderate price.

In the modificationshowninFig. the aux-, the pen is omitted, the

formed integral with the wall of the holder throughout a greater portion of its length,and has afbarrel or tubular portion, H', lat its lower end, adapted to fit in the opening in the end .y

of the pen-carrying plug; or, as represented in Fig. 7, the auxiliary feeders Ff might be made. in a separate piece and be inserted p in the pen-l arrying plug- It is evident that slight changes might be resorted to in theform and .arrangement of the severalA partsdeseribed without departing and scope of. my invention; myself strictly to the construction herein set forth; but,

Having fully described my invention, what I claim 'as new, Patent,. is-

The combination, with a hollow holder having one end permanently closed, and a main feeder permanently secured in the closed end of the holder and extending along the infrom the 'spirit terior of the holder toward the open end of the Same, of a pen-carrying plug adjustably secured in the open end of the holder and provided with a taper mouth adapted .to guide the free endof the feeder into Contact with the penistockjwhen the pen-carrying plug is ad justed for use,substantially as set forth.

2. The combination, with a hollow holder 'having one end permanently closed and `a penearryin plug adjustably secured in the `open end oft e holder and provided with a flaring opening in its end toward the holder, of .a feeder. permanently secured in the closed end of the holder and I bifnrcated point in engagement with the stock of the pen at the neclgof the flaring opening in the plug, substantially as set forth.

3. The combinatiomwith the hollow holder, of the pen-carrying and desire to secure by Letters provided with a'slotted .or
